CIGAR-BUNCH-ROLLING MACHINE.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Original application filed June 25.1904. Serial No. 21%,082. Divided and this application filed August 10. 1906- Serial No. 329,979.

To all whom it may concern:

Be it known that I, OSCAR HAMMnRsTmN, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Cigar- Bunch-Rolling Machines, of which the following is a specification.

This application is a division of my application No. 214,082, filed June 25, 1904.

My invention relates to cigar bunch rolling machines and has for its object to produce an apparatus in which the operations essential to the rolling of a cigar bunch may be performed inproper sequence and at the proper time interval. This object I achieve by means of the mechanism shown in the accompanying drawing which shows one form of my invention. It will be obvious however that my invention is not limited to the apparatus shown.

In the drawing: Figure I is a perspective view of the machine :Fi II is a plan view of Fig. I broken away to 0 early show the operatingparts for the rolling mechanism Fig. III is a sectional side elevation of the machine, the section being taken throu h the table. The parts are here shown in t e positions that they assume when the apron is ready to receive the bunch. Fig. IV is a fragmentary view similar to Fig. III showing the bunch in place :-Fig. V is a similar view showing the cross bars rollers or jaws as I shall hereinafter call them brought together and before the apron has been tightened to its full extent :Fig. VI shows the parts during the next stage of the operation wherein the apron has been drawn taut and the rolling is completed with the rollers or jaws in the position shown in said figure :Fig. VII shows the parts during the next stage of the operation where the jaws have been automatically opened as will be explained so as to permit the removal of the bunch from the apron In the drawing a represents a table of any desired or preferred construction. Bracket m secured to the said table serves to support the operating parts of the machine. This bracket m serves to support a cross-bar T. An apron 0 is connected at one end 1) and at the other end q to the cross-bar 1*, which cross-bar is adapted to be moved over the are shaped portion 8 of the bracket m, said are shaped portion being provided at either extremity with suitable stops 15. Fixed rollers a, over and around some of which the.

apron 0 passes are also supported. from the bracket 'm.

The actuating mechanism for the crossbar comprises an arm o pivoted at w and having abutments z z to engage the cross-bar r. The arm o may be swung by a foot-piece w, the counter-balance weight y being connected to the ivotal point w in order to aid in restoring tie parts to their initial positions shown in Figs. I, II and III.

The uppermost rollers, herein shown as a fixed roller u and a movable roller u, con stitute jaws for insuring the compression of the bunch after it has been placed in the bight 1 of the apron and to assist in rolling the bunch. These rollers or jaws are carried respectively as follows :-One roller 10 is carried by the bracket 'm and the other roller 10 is carried on an arm 2 which is pivoted at 3 and rovided with a roll 4 entering a cam slot 5 1n the arm c, which slot 5 is of special construction to effect the operations incident to eflicient rolling all in proper time, that is to say, to bring the jaws together at the proper time, to time and regulate the tightening of the a ron as to produce the best results, and to re ease the tension and open the jaws at the roper time. The special construction of this cam will be set forth hereinafter in describing the detailed operation of the machine.

In addition to mechanism for imparting a swinging movement, as hereinafter described, to the roller or jaw a, means are provided for tightening the apron so as to insure the eflicient operation of the machine. The means for tightening the apron comprises a belt tightening roller 7 mounted upon an arm 8 pivoted at 9 and provided with a roll 10 entering the cam slot 5 of the arm 0. weight 11 is provided pivoted at 12 for the purpose'hereinafter mentioned to constitute a locking nose.

It will be readily understood that swinging the arm 1) will cause the cam slot 5 to act upon the rolls 4 and 10 to operate the jaws and the tightening device. It will also be obvious that movement of the cam 5 will effect these movements but the most important feature is the timing of the movements. It is desirable that the jaws or rollers be closed or brought together and a movement of the apron initiated before the final removal of the bunch from the machine. willthus be observed that the cam 5 effects tightening of the apron takes place. This is accomplished by the peculiar shape of the cam slot 5. It will be observed that this slot is constituted of cam surfaces 5, 5 ,'5, 5, to impart the various movements in proper time. These movements are efiected as follows: Starting with the parts in the position shown in Figs. III and IV, with the bunch l8 and binder 19 in place, the first effect of the movement of the cam 5 will be to bring the roll 4 operating the movable jaw or roller it into the portion 5 of the cam 5, thus bringing the movable jaw or roller in proximity to the fiXed jaw or roller to close the loop in the apron. At the same time a slight tightening of the apron iseifected as the roll 10 governing the tension of .the apron moves over the cam portion 5 of the cam 5 and is. about to enter cam portion 5 of the said cam. At this instant the roller 10 enters the cam portion 5 and as the movement of the cam continues the roller 10 traverses the portion 5* of the camv and firmly tightens the apron. Itwill be understood that after the closing of the j aws. and during the slight preliminary tightening and before the final tightening the apron 0 has begun to move. This .movement of the apron is brought about by the engagement of the lefthand abutment z with the cross-bar r. It-is desirable that the final tightening should not take place until therolling operation-is initiated, as such tightening would cause the rollers u, u to bind and theresultwould 'be unsatisfactory. It is for thisreason that the cam surfaces 5 and 5 are arranged as shown.

The .parts have now assumed the positions shown in Fig. VI wherein the rollers l and 10 are shown as traversing the portion 5 of the cam and the rolling of the bunch is being effected.

The cam continues to move and the rollers finally come into the positions shown in Fig. VII wherein the rollera is shown as having run into the portion 5 of. the cam. and resting 'behindthe weighted cam latch-11, while the roller 10 rests beneaththe latch 11. The effect of these last mentioned movements is to separate the jaws orrollersv and to permit tlge t the following operations viz:-a.closing of the j aws, accompanied by a slight tightening of the apron, then=the apron begins tomove and is subjected to further tension and finally there is an opening of the jaws and release of the tension at the completion of the rolling operation. These operations are-all performed automatically and harmoniously owing to the peculiar'shape of the cam.

Having described my invention, what I claim and desireto secure by Letters Patent 1.
